Privacy

What we collect

Nothing, on purpose. MakerCalc has no accounts and performsno server-side data collection. Every calculation runs locally in your browser — the numbers you type are never sent anywhere.

Local storage

The filament library, printer profiles, saved quotes and the current calculator draft are stored in your browser's local storage (makercalc.* keys) so they survive reloads. This data never leaves your device unless you export it yourself (JSON backup) or share a quote link, which contains that quote's values in the URL. Clearing your browser's site data deletes it permanently.

Analytics

If analytics are enabled, we use a privacy-friendly, cookie-less analytics tool that counts page views in aggregate only. It does not track individual visitors and no personal data is stored.

Advertising

The site may display ads served by Google AdSense in the future. Ad networks may use cookies or similar technologies; where required, a consent banner will be shown before any such cookie is set.

Affiliate disclosure

Some links on this site are affiliate links. If you buy a product through one of them, we may earn a commission from the retailer — at no extra cost to you. Prices are identical whether you use our link or not, and commissions never influence the calculators' results. This disclosure is made in line with FTC guidance and EU consumer-transparency rules.

Offline use

MakerCalc installs as a PWA and caches its pages on your device so it works offline. That cache lives only in your browser and can be cleared at any time from your browser settings.
